Is it normal for my breasts to leak milk?

Yes, some nursing moms leak or spray milk from their breasts, especially when their breasts are full. Leaking is most likely to happen in the morning (when milk supply is at its peak) and during feedings (when one side leaks while the baby is nursing from the other side).

Some nursing moms leak only during the early weeks of breastfeeding, while others leak until their baby is weaned. For some women, leaking starts during pregnancy.

What causes my breasts to leak?

Your breasts may leak when they become so full of milk that they overflow. (Leaking is common in women who produce more milk than their baby needs). Or you might leak when your letdown reflex – which releases the milk – kicks in.

In the first weeks of breastfeeding, your letdown reflex is being conditioned to respond to the sensation of your baby nursing. Until your reflex adjusts to that stimulation, certain sensations and even thoughts may trigger letdown. For example, hearing your baby cry, thinking about your baby, smelling your baby, or sitting in the chair where you usually breastfeed might be enough to trigger your reflex and cause leaking.

Here's how it works: These stimuli prompt your body to release oxytocin. This hormone makes the milk-making lobes of your breasts contract and eject milk toward the nipple. If your baby isn't nursing at that moment, the milk may leak or even spray.

Oxytocin also causes the contractions felt during orgasm, so your breasts also may leak or spray milk during sex. (You may want to bring a hand towel to bed.)

What can I do about my leaking breasts?

If you're producing too much milk in the early days of nursing, be sure to nurse frequently – before your breasts become too full.

If your breasts are full but your baby isn't ready to eat, it may help to "pump to comfort." This means pumping just enough to make your breasts compressible and comfortable, but not so much that you boost your milk supply. Manually expressing a little milk is another option.

You'll soon establish a breastfeeding rhythm that works for you and your baby. Once you're in sync with each other, you'll probably produce just the right amount of milk for each upcoming feeding.

Here are other ways to deal with leaking breasts:

Apply pressure. If you feel letdown happening at an awkward moment (like if you're chatting with a co-worker about your baby and your milk starts to drip), cross your arms over your breasts and press firmly. If you're sitting at a table, cup your chin in your hands and press your forearms into your breasts.

Use nursing pads. Tuck nursing pads inside your bra to absorb leaks. You can buy disposable or cloth pads online or at the drugstore. Or make your own cloth pads from cut-up cloth diapers. Be sure to change the pads when they get damp so bacteria and fungi won't grow on your nipples. (A warm, moist environment can lead to fungal infections, such as thrush.)

Be prepared. If one breast always leaks when your baby is nursing on the other, put a cloth over that breast or a nursing pad inside your bra ahead of time.

Dress for leaks and pack extras. When you're out and about, bring along some nursing pads and extra top. (Try wearing prints – they're great for camouflaging milk stains.) Or carry a jacket or sweater that you can throw on if you notice your breasts leaking.

How long will my breasts keep leaking?

Some women continue to leak for as long as they're nursing, but many find that the problem goes away once their baby gets the hang of breastfeeding – usually within the first six to 10 weeks.

In the meantime, remember that your leaking breasts are a sign of your body's efficiency making milk for your baby. (And don't worry – when the leaking eventually stops, you'll still be making plenty of milk to meet your baby's needs.)
